* Fixes issue where BidPrice/AskPrice were not adjusted for Quote Ticks
* Previously, ticks would have their prices (Tick.Value) adjusted whenever
TickType == TickType.Quote, but would not have their
BidPrice/AskPrice fields adjusted, thus potentially being orders
of magnitude such as 4x from the actual Bid/Ask prices.
This commit applies the pricing scaling factor in a critical
path where Ticks are adjusted to their scaled price. This issue
only applied to Resolution.Tick && SecurityType.Equity data.
* Refactors Extensions Tick Scale extension method
* Adjusts unit test to dispose of resources and assert history count
* Replaces use of FileSystemDataFeed for NullDataFeed in Adjustment test
* Adds regression algorithm testing BidPrice & AskPrice adjustment
* Address review: remove SecurityType check on TickType.Trade adjustments
